ADJUSTABLE SUPPORT FOR THE CLOTH-WHEELS AND BURR-WHEELS OF ROTARY KNiTTING-MACHIN ES SPECIFICATION forming part of Letters Patent No. 508,452, dated November 14, 1893.

Application filed October 3, 1892.

To all whom itmay concern.-

Be it known that I, EUGENE VERMILYEA, of the village of Waterford, county of Saratoga, State of .New York, have invented new and useful Improvements in Adjustable Supports for the Cloth-Wheels and Burr-Wheels of R0- tary Knitting-Machines, of which the follow ing-is a specification.

My invention relates to mechanism where-. by the sinker-burrs and cloth-Wheels of rotary knitting machines when mounted upon a standard that is upwardly projected from the machine table or bed, are each made separatelyadjustable with relation to the needles and cloth; and the object and purpose of my invention are to so arrange and oonstructthesinker-burr standard supports that the burrs as held in an elastic engagement with the needles may be moved toward or from the latter, or may be deflected either to the right or left by a rotationof its holder, or so that the burr may be raised or depressed on an angle where adjacent to the needles; and when so adjusted may be secured in such desired-position, and with the cloth-wheel support so arranged that the wheel may be raised, -or depressed, or caused to engagewith the cloth inside of the needles at such angle as is desirable; or to be moved laterally so as to bring the landing wheel and'presser-wheel close up to the sinkerburr.

Accompanying this specification to form a part of it there are three plates of drawings containing seven, figures illustrating my invention with thesame designation of parts by letter reference used in all of them.

Of the illustrations Figure 1 is a side elevation of the apparatus containing my invention shown as applied to a knitting machine, which latter is shown in part. Fig. 2 is a central vertical section of the apparatus taken from end to end with the burr shown as turned up abnormally and away from its engagement with the needles. Fig. 3 is a front elevation of the mechanism. Fig. 4 is a perspective of the standard to which the mechanism attaches. Fig. 5 is a perspective of a bracket that attaches to the front of the standard when in position. Fig; 6 is a perspective of the shaft on which the arm that supports the burr-holder is hinged or pivoted and on which Serial No. 447,606. (ll'o model.)

The letter B designates a bracket made with a vertical slot M, by which said bracket when vertically adjusted to proper position on the standard is secured thereon by'a threaded bolt d, made with a nut-form head I.

The letters -E designate ears formed on the sides of the bracket oppositely, and vertically; and the letters b bearings oppositely formed in the ears E to be horizontally in line for the journals J of the shaft'S when placed thereon, one of said journals being threaded to enter the tapped end of said shaft for its insertion in its bearings. I

The letter N designates a set-screw, tapped and threaded into one of the front ends of one of the ears E, so that when said-set-screw is screwed in, it will .engage with one of the journals of the shaft S and prevent it from turning. V This shaft S is centrally, and at its top and bottom, made with recesses R,

which have flat parallel surfaces, and a cen- 8 5 tral passage 19 made through the shaft at right angles to the inner surfaces of the recesses R.

The letter A designates a vertically arranged arm that at its lower end is made with 0 a shoulder h, and where reduced in diameter by the formation of the shoulder, this arm passes through the passage 10 made in the shaft S with the shoulder h, of the arm A,

resting upon the flat surface of the recess R, 5

made in the top of said shaft S and where extending through said passage 10?, is threaded to receive a nut 11?, and keeper k.

The letter O designates a clamp formed on the upper end of the arm A, said clampbe- [co ing made with a circular passage p and pinch-screw 1 The letters. l-I. designate the burr-holder cylinder, that is placed within the clamp passage p of the arm A, and held there by the pinch screw and this cylinder has an interiorly constructed and encircling recess its, in which is placed a spiral spring 712, with one end of the latter bearing against the end 8 of the recess h.

The letter 7& designates the burr-holder proper, which is arranged within the cylinder H, and is made with a shoulder 7L against which latter the end 6 of the spring 7L2, bears, so that when said burr-holder proper is moved outwardly it is so moved against the force of said spring. The outer-end of this burr-holder proper is threaded at t and has threaded thereon the jam-nut h, and the adjusting nut If, by which the burr-holder proper may be regulated as to its adjustment radially to the needle cylinder and by which also the force of the spring encircling it is controlled. The inner end of the burrholder proper has formed thereon an offset extension 7L8, to receive the spindle h, and the sinker-burr B The letter O designates a slot made in the standard S, through which the holder cylinder H, and the burr-holder proper may be moved when raised or depressed at the outer end. As thus made and arranged through the sliding connection it makes with the arm A, and the journaled connection the latter makes, with the bracket B, theburr-holder may be raised or lowered to bring the blades of the sinker-burr in longerorsliorterengagement with the needles, and by means of the set-screw N the position of the burr relative to the. needles may be secured as adjusted; and by means of the connection the burrholder. makes with the clamp 0 the holder and its cylinder may be turnedin said clamp to, vary the position of the burr-blades to the needles and be secured as adjusted by the pinch-screw 11 The letter 'W, designates a cloth-wheel having a disk-form and made with a frontwardly projecting sleeve 40*. The letter 10 designatesa spindle on which said wheel and its sleeve,v turn, said wheel being secured on said spindle by a nut to, on the inner end of said spindle, and a collar 10 having a set-screw 10, so that the wheel is free to turn on its spin' dle from the traction engagement it makes with the moving cloth.

The letter K designates a clamp formed on the. outer end of the spindle 10 The. letter A designates a crank-form arm,-

the upper and vertical end of which as indicated at a is inserted in the clamp K, and on which the latter and its spindle 10 may be, raised or lowered to elevate or depress the cloth-wheel W, and held as so adjusted by thepinch-screw y, of said clamp K.

The letter a designates the horizontal extension ofvthe crank-form arm A that is made to journal in a horizontal bearing I), made in the bracket-form projection upcast from the standard S. This bearing is constructed with a set-screw T, that is tapped and threaded into said bearing so that it will engage with the arm a, where ournaling within the latter, and in wh1ch,when the setscrew therein is free from the ournal part, said arm may be moved horizontally therein, and secured by the set-screw when ad usted, and by which construction the cloth-wheel may be moved laterally and positioned with reference to the needles and the landlngwheel (not shown) as may be desired. As thus made and arranged the sinker-burr may be positioned so as to have the needles enter deep between the burr-blades so as to leave little play and thus produce short stitches, or to enter the upper part of the space between the blades so as to make a long stitch according to the pitch at which the burr-blades are adjusted by myimprovement; andwhen l ve yarn or silk is used and it is desirable to bring the presser-wheel and landingwheelas close to the sinker-burr as possible, the cloth wheel,

by my improved construction,may;be,moved laterally to thus admit of suchrplaclng ofthe presser-wheel and landing wheel with,reference to the sinker-burr. I

Having thus described my invention, what I claim, and desire to secure by LettersRah out, is- I 1. The combination with the-cyhnderofi a rotary knitting machine, oi a standard up wardly projected from the machinetable a crank-form arm having a horizontal partjour. naled into an offset from sald standard, 1n. which the said horizontal part o-flsatdcrank form arm can turn or be move horizontally;
